They are taken from IPv6 Router Advertisment DNS option. That means
your device should have IPv6 connectivity also, check with e.g. 'ip
addr'.

Thank you, you confirm what I had supposed.
I understand that this is not a connman problem, but is there a simple
way to check what is sent by isc-dhcp-server ?

What is surprising anyway is that on my local nerwork, I have this
problem only with PC using connman, not with those which use resolvconf.
Maybe I sholuld disable IPV6 (wich is not used, even if maybe enabled by
default, in my local network) at connman level. Is it possible ? I am
lost in connman doc.

While connecting to wifi using conmann, I noticed that "ready" is much faster
than "online".
My question is what's the difference b/w "ready" and "online"?
If a wifi connection is "ready" can I connect to the Internet?
I'm trying to determine whether I should use "ready" or "online" to determine
whether a connection is successful.
"ready" would be better because it's faster.
Thanks.

Hi Frederick,
Ready means that your connection has received full IP configuration (most
likely from dhcp).
Online is (by default) achieved by ConnMan making an http get request to:
#define STATUS_URL_IPV4 "http://ipv4.connman.net/online/status.html";
or
#define STATUS_URL_IPV6 "http://ipv6.connman.net/online/status.html";
Depending on your network speed, and distance to connman.net, this can take a
short while.
In fact, if you are unlucky with the state of the internet it might even fail
completely. This would happen as well if your firewall is blocking outgoing
port 80 connections to the internet (I had that rule with a corporate firewall
in one company).
A service is usable in the Ready state. Although if the online check fails, the
top/default service might get "downgraded" and default routes might get
deleted. Especially if you have more than one connection available (e.g.
ConnMan might fall back to Ethernet). In that case you may end up with just a
local subnet route.
